CHARLES E. SMITH, 0F BROOKLYN, NEW YORK, ASSIGNOR TO REMINGTON TYPE- WRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPEWEITING MACHINE.

Original application filed April 6, 1922, Serial No. 550,045. Divided and this application filed January 11 To all whom it may concern.

Be it known that 1, CHARLES E. SMITH, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the countyof Kings and State of New York, have-invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting and like machines and more particularly to sooalled portable machines intended to be inclosed and transported in a carrying case.

The main object of my invention, generally stated, is to insure a proper conditioning of a portable machine for transportation.

In such machines it is highly desirable to release the carriage from restraint of its escapement or feed device before the machine is inclosed in its carrying case, and to maintain the carriage thus released until themachine is about to be used, when it is desirable to reestablish the connections by which the carriage is restrained'by its feed mechanism. This is in order that the weight ofor jolts from the carriage, while the machine is being transported or carried in its case, may not be exerted on the carriage feed devices and which, if so exerted, might result in injuring or breaking said devices.

This is one of the factors that enters into consideration in conditioning the machine for transportation, and which is taken care of by my invention. Another factor is the necessity of placing the carriage in a cen tered position in its line of travel in order that the close fitting cover of the case may be closed without interference from the machine and to hold or lock the carriage against traveling movement from such centered position when it'is released from the restraint of its feed devices.

By my present invention I provide simple and highly effective improved means for accomplishing these results, such. means being necessarily actuated to free the carriage from restraint of its escapement devices before the case can be closed and necessarily actuated to re-establish such restraint of the carriage by its escapement devices before the machine can be actuated. I also provide means by which the centering lock is necessarily rendered effectii e and ineffective.

To the above and other ends which will hereinafter appear myv invention consists Serial No. 611,922.

in the features of construction, arrangements of parts and combinations of devices,

set forth in the following description and particularly pointed out in the appended claims.

This case is a division 01 my application, Serial N 0. 550,045 filed April 26, 1922.

I have shown my invention in the present instance embodied in a Remington portable machine, many of the features of which are shown in the following patents and pending applications A. V. Smith, Pt. No. 1,342,513, dated June 8,. 1920; J. B. Holden, Pt. No. 1,386,256, dated Aug. 2, 1921; J. B. Holden, App. Sr. No. 469,458, filed May 14, 1921; J. B. Holden, App. 'Sr. No. 541,355, filed Mch. 6, 1922; J. B. Holden App. Sr. No. 547,128, filed hitch. 27, 1922; G. A. Seib, App. Sr. No. 529,415, filed J an. 16, 1922. It should be understood, however,- that the invention is not restricted to embodiment in a machindand rearwardly striking type bars (not of this style.

From certain aspects of my invent-ionit is in the nature of improvements on the construction disclosed in therabove mentioned Holden application, Sr. No. 547,128.

The Remington portable machineis pro vided with a carrying case, the cover of which 'can be closed only when collapsible parts of the machine are moved to compact relation with the remainder of the machine and whereas carriage is properly" centered shown) on the upper side thereof.

The step-by-step feed movement of the carriage is controlled by escapement mechanism comprising, in the present instance,

wardly and forwardly bent arms 21 and 22.

for locking the carriage in a centrally dis posed' position on the machine in order that the cover-of the case-ma becbsed, and the feedi'ack is moved to releasing position by hand-and is] maintained in such position by a separately actuated collapsible partpf th'e machine, such -as 'th'e finger wheel of the platen;- By my pr'esent invention, 1 provide improved "means for locking the carriage ih -itsmeiit'ered positionwhich are auto matically a tuated or rendered "effective by a oompactible part of the machine and which must necessarilybe actuated before the"case can be" closed I also provide automatically operating means "for Y releasing-the -carriage from the restraint of itsfeethdevicesby the same" operation of said comp actible part.

The arm 21 is bent at its free end portion to form a pivot bearing23 that reeeives a I pivot rod 24;;such rod being supported in bearings 25 of a bracket which issecured to the these plate 13 0f the carriage. Thear-n'r 22 1s'secured by a screw 26 to a block 27,

aperturedto receive a pivot rod 28 ;'such rod being supported in bearings 29 of-a bracket plate 30, secured by screws 31 to the base plate 13 of the carriage.- Coiled springs 32 surround the pivots 241 =and 28and-each bears at one end 33 on theassociated bracket plaiteyand at its other 'end-34t against the shown 1I1 F1gL'2. Therack is limited in its In" the'-ac'companying" drawings I have shown' only 'so 'much of the Remington portable machine as is necessary to arrive at an understanding of my inventionin its embodiment" therein;

The outer sheet'metal framed otthe machinecontains an inner sheet met al frame 2 i comprises a carri'age support 3 pivoted at 4 as showninFigs. 1 and2.

on' upright arms 5 secured to a rock shaft 6 pivotedat its ends, as at 7 to the inner frame-,so that-the carriagesupport may receive a case shifting movement fore-and-aft of the machine! The carriage" support "has two grooved guide railsor plates8 and 9 secured thereto. These" guide-rails contain crossed. bearing rollers ldthat are' received in'wvays in the rails 8 and '9 and in companion grooved rails or ways 11, and 12 respectively formed movement in this direction 'by' the arms 21 and '22 bearing I against the rear ends of two screw stops and 36 respectively, threaded into tapped openings in the bent-"edge portion 12'of thecarriage baseplate. 1 Fixed at an upwardly and rearwardly extending feed rack releasearm- 38,-which terminates'in a One ofthe collapsing parts of the Helm in gton portable machine is the finger wheel 12, which is movable from the dotted line position. of use, to the" full line compact po sition shown in 'Fig. 3, aspointed out in the" hereinbofore mentioned application, S1; N'o.- 547,128. Referring particularly to Fig- 6, it will be seen that the -finger wheel 42 is fixed by a screw 13 to a spindle'or platen shafted which is movable longitudinally in the right-hand platen head 45; a :spline 46 on the latter extending into a spline/groove 47 in the spindles Screws .45 secure the platen l1ead 15 to the core of the platen 16. A pin 48ion 'the spindle coactswvith the spline 416' to limit the outwand movementof the spin dle and finger wheel, 'asshown. Aflanged bearing. sleeve 49 surrounds the spindle 44 and-is supported in anopeni'ng in the righ t'- the platen is mounted in the platen carrier.

or carriage, and the finger wheel 42 is connected to turn with the platen but may be moved longitudinally thereof from the full to the dotted line position in Fig. 3, or vice versa.

The sleey'e 51 has a laterally extending slot 52 cut therein to a point where it crosses the bore 53 in the sleeve. A sheet metal member or finger 54 is received in the slot 52, and has a movement therein transversely of the spindle 44 from the positionshown in Fig. 1, to that indicated in Fig. 2, or vice versa. When the finger wheel is in the expanded or dotted line position shown in Fig. 3, the left-hand cone-like end of the spindle, indicated at 44 in said figure and in Fig. 6, is positioned to the right of the lateral slot 52. The pointed end portion 44 is in the nature of a cam which coacts with a rounded edge 54 of the member 54 and shifts it from the Fig. 2 to'the Fig. 1 position when the finger Wheel 42 is moved to the compact or full line position shown in Fig. 3. During the last portion of the movement of the finger wheel to this position the cylindrical portion of the spindle 44 will be brought into co-operation with the finger 54, and

- prevents the latter from returning to the Fig. 2 position so long as the finger wheel remains in the pushed in, or compact position.

In the present instance the finger 54 constitutes part of a sheet metal controlling member, designated as a whole by the reference numeral 55. As will be seen upon reference to Fig. 4, this member is pivoted on the shank of an interiorly threaded, headed screw 56, screwed onto a shoulder screw 57 that passes through an opening in the end plate 15. A spring 59 is wound around a pin 60 projecting from the outer face of the end plate 15, and it is anchored at one end, as at 61, whereas the free end 61 of the spring bears against a projection 58" which if desired may be in the nature of a finger piece on the member 55. This projection 58 is bent inwardly or to the right back of the carriage release arm 38, as in the Remington portable machine, so that a forward movement of the arm 58 carries with it the arm 38, thus efi'ecting a release of the carriage from restraint of its feed devices. The force of the spring 59 is exerted to return the controlling member 55 to the Fig. 2 position when it is freed from restraint ofthe spindie 44 by moving the finger wheel'42 to the i dotted line position in Fig. 3. The free end of the finger 54 coacting with the bottom wall of the slot 52 limits the movement of the member 55 in this direction.

The controlling member 55 also carries a locking finger or device 62 which constitutes one member of a lock for locking the carriage in a centralized position on its support 3, as shown in Figs. 1 and 3. This finger 62 registers with a slot 62 in the base plate 13 of the carriage and is adapted, at

any point in the travel of the carriage, to

be moved through said slot from the inefi'ective position shown in Fig. 2, to the effective position shown in Fig. '1. In this last mentioned position, the lower edge portion of the locking finger 62 extends into cooperative relation with the companion looking member carried by the carriage support 3. If at this time the carriage be moved in either direction of its travel from an offcentered position, the locking members will coact when the carriage reaches the centralized position on its support, and will automatically lock the carriage against movement from such position in either direction. The companion locking memberon the support 3 is shown'detached in Fig. 5, and in the present instance comprises a strip of spring metal 63 fastened by a headed screw 64 to the under side of the support 3; the stem of the screw passing through an opening 65 in the locking mem ber. From one edge of the strip 63 is bent an upwardly extending detent 66 having a slot or recess 67 therein. The upper edge of the detent is beveled outwardly and clownwardly in opposite directions from the side walls of the recess 67, as indicated at 68. The detent 66 projects up through a slot 69 in the left-hand end portion of the support 3, so that the beveled edge portions 68 of the detent extend above the upper side of the member 3, and are normally maintained in such position by the inherent resiliency, or spring pressure, of the strip 63. The construction is such that when the locking finger 62 is in the effective position, and the carriage is moved in either direction towards a centralized position, it will bring the lower edge of the finger 62 against one or the other of the two bevels 68 and flex the detent downward. Vhen the centralized position, shown in Fig. 3, is reached the recess 67 will register with the finger 62 and the detent 66 will spring upward so as to engage the locking finger on both sides by the side walls of the recess 67, and thus prevent a movement of the carriage in both directions. TVhen, however, the member 55 is moved to the Fig. 2 position, the finger 62 will be withdrawn from the recess 67 to 'free said finger from the detent, and the riagedstherefore free to beimoved ,in ,either. directiom ofn itsi..:travel,i somfar as the centralized locking means arezconcernedi The carrying. caseiofi the Remington aport- 5 able machine. comprises a bae+board 70,

The claims of said parent application are restricted to features of construction not disclosed in this case. a

By my invention I have provided simple means that not only automatically effect the release of the carriage from restraint of its escapement before the machine can be inclosed in its case, but also automatically render the center lock effective and compel the proper centering and locking of the carriage by the members 62 and 66 before such a result can be obtained. I therefore insure a proper conditioning of the machine before it can be inclosed in its case for trans portation, and prevent injury to the parts of the machine that might result except for such proper conditioning.

Various changes may be made Without departing from the scope of my invention as defined in the accompanying claims and various parts may be used Without others.
